1. Nicolás Paez | @inicopaez | nicopaez@computer.org Consideraciones de diseño para un modelo de infraestructura Octubre 2018 | ArqConf
2. Modelos de Infraestructura Resumen: De la mano de DevOps, SREs y un conjunto de herramientas, la práctica de Infraestructura como Código ha adquirido una gran popularidad en los últimos años. La adopción de esta práctica implica una toma de decisiones que entre otras cosas incluye el diseño de un modelo de infraestructura y la selección de herramientas asociadas. En esta sesión veremos un conjunto de conceptos y recomendaciones para tomar estas decisiones de cara a una efectiva implementación de la práctica de Infraestructura como Código.

28. Virtual Machines vs. Containers
29. Challenge #2: Mutable vs. Inmutable
30. Mutable Infrastructure Test You package your app and make it run on different infrastructure Prod app-v1 app-v1 app-v1 OS OS OS Runtime Runtime Runtime
31. Mutable Infrastructure Test You package your app and make it run on different infrastructure Prod app-v1 app-v1 app-v1 OS OS OS Runtime Runtime Runtime app-v2 app-v2 app-v2
32. Immutable Infrastructure Test You package your app with its infrastructure Prod App-v1 + Runtime App-v1 + Runtime App-v1 + Runtime OS OS Engine OS Engine Engine
33. Immutable Infrastructure Test You package your app with its infrastructure Prod App-v1 + Runtime App-v1 + Runtime App-v1 + Runtime OS OS Engine OS Engine Engine App-v2 + Win2016 App-v2 + Win2016 App-v2 + Win2016
34. Challenge #3: Tools Selection
35. Automation Layers Layer 2: base software (db engine, web server, app server) Layer 1: OS & Networking Layer 3: Apps (binaries, configuration, data)
36. Automation Layers Layer 2: base software (db engine, web server, app server) Layer 1: OS & Networking Layer 3: Apps (binaries, configuration, data) Ansible, Chef, Puppet, SaltStack Terraform, Vagrant, CloudFormation Jenkins, TeamCity, Spinnaker
